Using linear function concepts, it is found that the volume of each marble is of 0.05 liters.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The linear function that gives the volume of water, when n marbles are inserted into the tank, is given by:
w = 32 - 0.05n
The slope of -0.05 means that for each marble inserted, there are 0.05 liters less for water, hence the volume of each marble is of 0.05 liters.

What is the focus of a parabola with a standard form of y = 1/4x^2 - x - 1?
Include an explicit reasoning, just giving an answer won’t be helpful
Answer:
(2, -1).
Step-by-step explanation:
y = 1/4x^2 - x - 1
First convert to vertex form:
y = 1/4(x^2 - 4x) - 1
y = 1/4[(x - 2)^2 - 4] - 1
y = 1/4(x - 2)^2 - 2
The formula for the focus of the parabola y = a(x - h)^2 + k is (h, k+1/4a)
So here it is:
(2, -2+1/ 4*1/4)
= (2, -1).

Suppose the risk-free rate is 3.2 percent and the market portfolio has an expected return of 9.9 percent. the market portfolio has a variance of .0282. portfolio z has a correlation coefficient with the market of .18 and a variance of .3185. according to the capital asset pricing model, what is the expected return on portfolio z?
Beta = Correlation x (Variance of Z)^0.5 / (Variance of Market)^0.5
Beta = 0.18 x (0.3185)^0.5 / (0.0282)^0.5
Beta = 0.604927
CAPM equation:
Expected return = Risk free rate + Beta x (Market return - Risk free rate)
Expected return = 3.2% + 0.604927 x (9.9% - 3.2%)
Expected return = 7.25% is the answer.
Portfolio return refers to the return or loss realized on an investment portfolio that includes multiple types of investments. The portfolio is intended to provide returns based on the defined objectives of the investment strategy and the risk tolerance of the type of investor covered by the portfolio.
The basic formula for expected return is to multiply the weight of each asset in the portfolio by the expected return and then add up all these numbers. In other words, the expected return of a portfolio is a weighted average of the returns of the individual components.

b)The pool is filled with water at a rate of 2 m³ per minute. How long will it take to fill the pool?
At a rate of 2 m³ per minute, it would take 212.5 minutes to fill this swimming pool.
The shape of the pool.Based on the information provided, we can logically deduce that the shape of this pool is a prism because it is deep (2.2 m) at one end and shallow (1.2 m) at the other end.
How to calculate the time?First of all, we would determine the volume of this swimming pool as follows:
Volume = 1/2 × (1.2 + 2.2) × 10 × 25
Volume = 1/2 × (3.4) × 250
Volume = 1.7 × 250
Volume = 425 m³.

Answer:
y = (1/3)x + 7
Step-by-step explanation:
The general structure form of a line in slope-intercept form is:
y = mx + b
In this form, "m" represents the slope and "b" represents the y-intercept.
The slope of a perpendicular line is the opposite-signed, reciprocal of the original line's slope. Therefore, if the slope of the original line is m = -3, the new slope is m = 1/3.
The y-intercept can be found by plugging the new slope and the values from the point (-3, 6) into the slope-intercept form equation.
m = 1/3
x = -3
y = 6
y = mx + b <----- Slope-intercept form
6 = (-3)(1/3) + b <----- Insert values
6 = -1 + b <----- Multiply -3 and 1/3
7 = b <----- Add 1 to both sides
Now, that you have the slope and y-intercept, you can construct the equation of the perpendicular line.
y = (1/3)x + 7
